CAREER: Fluctuations, Dissipation, and Phase Transitions in Vortex States of High-Tc Superconductors

W：这是一份给年轻教员的职业助学金，将研究和教育结合在一起。该理论项目将解决高温超导体现象学中的两个主要问题：(I)涡旋液体的平衡和非平衡性质，目的是推导目前假定的流体动力学描述，并在存在平行于外加磁场的电流的情况下阐明涡旋状态、不稳定性和耗散；(Ii)涡旋液体到固相的冻结转变，这将包括发展一种新的平均场描述，该描述明确地显示涡旋有序成晶格的能量趋势，并可概括地包括涨落的影响。这些研究工作将得到教育部分的补充，通过开发新课程，并让所有级别的学生参与研究。%这是给一名年轻教员的职业助学金，用于一个研究和教育相结合的项目。理论研究将集中在高温超导体中出现的独特物质状态的性质。教育部分将侧重于课程开发和将所有级别的学生纳入研究计划。

w:\awards\awards96\career\0formca.doc 9625111 Radzihovsky This is a CAREER grant to a young faculty member which combines research and education. The theoretical project will address two major problems in the phenomenology of high temperature superconductors: (i) the equilibrium and nonequilibrium properties of the vortex liquid, with the goals of the derivation of the currently assumed hydrodynamic description, and elucidation of the vortex states, instabilities and dissipation in the presence of currents parallel to the applied magnetic field; (ii) the freezing transition of the vortex liquid into a solid phase, which will consist of the development of a new mean-field description that explicitly shows the energetic tendency of the vortices to order into a lattice and which is generalizable to including the effects of fluctuations. These research efforts will be complemented by the educational component through new course development, and incorporation of students at all levels into research. %%% This is a CAREER grant t a young faculty member for a program which combines research and education. The theoretical research will focus on the properties of unique states of matter which occur in the high temperature superconductors. The educational component will focus on course development and integration of students at all levels into the research program.
